The symptoms you describe are exactly what she went through. She did recover but always leaned a bit to the left, and at first couldn't negotiate doorways very well, but she acclimated to her world being off kilter. She lived for many years after her stroke. Everyone called her Tilt instead of her name afterward... none of us really liked her name very much, and the nickname Tilt was made in a loving way.
I was a kid at the time, so I don't remember if she took any meds at first or anything. But she did get better and pretty quickly though it was both sad and humorous to see her trying to steer herself through doorways and get her head in the food dish or water bowl until she got that figured out. She got quite good at figuring out how to steer more to the right so that after awhile she could even run without crashing into anything. She was actually a lot more endearing after her stroke with that kooky little tilt to the left, and she even became rather more friendly (she was not a very nice kitty before... she more or less just grudging tolerated everyone including the other pets).
Don't despair. It's very scary to see when it first happens... I definitely remember that. We all were so certain that she'd have to be put to sleep when my parents took her to the vet, and we'd never see her again. We were really shocked that they brought her home and that she expected to fully recover other than that wee bit of tilt.
